A method comprising the steps of: using a drillpipe to install a test plug into one end of the throughbore of a blowout preventer (BOP); using a valve in the BOP to isolate the opposite end of the throughbore of the BOP, using piping to connect the output of a cementing unit to the throughbore of the BOP; using the cementing unit to increase the pressure in the throughbore of the BOP to a predetermined level; displaying the pressure in the piping as a function of time; and displaying the pressure in the piping as a function of time for the same blowout preventer system at an earlier time when leakage was deemed to be within predetermined acceptable limits. The pressure decline in the BOP system is quantified by the fluid PVT behavior, mechanical influences, and thermodynamics of pressurization and subsequent cool down. The pressure decline caused by a leak can be detected reliably and efficiently with high-resolution pressure data.
